Sorry for your problem, I think there was a small mistake before installing CM11, and was what you describe in step 3 "Did a System Reset" when the installation instructions say: "Wipe data, cache, and dalvik cache". I'm afraid you can only recover your VIVID through JTAG on any site that offers the service, it seems you deleted your operating system. The other option is to try [unbrick] HTC Unbricking Project By dexter93 developers forum, http://forum.xda-developers.com/show...php?t=1627886;
All the best. Just a recommendation, read, read and read each post and comments to take no surprises. Good luck.:fingers-crossed
I would appreciate your comments

Please... Do not scare people like that...

AFAIK... You only need a JTAG if your phone reads qhusb_download... Or something like that...
